From around 1966. The original speaker, which is likely to have been a Celestion T1088 (silver alnico), has gone, but the original wiring loom with Rendar jacks remains. On the upper back panel, the standard keyhole-shaped holes for hanging the unit on nails or screws on a wall.

The cut-out for the speaker has two cross-bars (vertical and horizontal). Earlier cabinets generally only had a single vertical. No logo was ever fitted to the unit below - there are no holes and no signs of glue.
